It is possible the files are corrupt. I will check and notify here is that is the case.

However, his often happens when the server is extremely busy as is the case right now. It can also happen when more than one file is downloaded at a time.

My suggestion is to wait 'til the feeding frenzy has died down a bit.

Yep. I believe that's good advice. I downloaded 8 on my Mac and only 2 could be opened. Since people seems to be having problems with different files, while others can open them, it doesn't seem likely to be a file corruption problem.

I guess the main reason for the corrupted ZIPs is a interrupted/not finished download. Just have a look at the downloaded file's size and the size that is stated in the shop. If they differ, your download did not finish correctly...

Exactly. The server is probably overloaded in several ways and should be (re)configured to allow less download connections. Bandwidth and time is wasted by downloads that don't complete and have to be restarted.

Did just fine down loading file until 11,12 & 13. Those would only get so far then just crash (fail).Tried a number of times to down load, however same problem occurs.I assume it could be demand that is overloading the server.
